| 英文摘要 | Nano-sized silicon nitride powders were synthesized through the reduction of silicon tetrachloride (SiCl4) by sodium in liquid ammonia at around -40 degrees C. The product was in uniform particles of several nanometers, and in the amorphous form. The amorphous structure was stable up to 1200 degrees C and turned to the crystal structure of alpha-Si3N4 at 1300 degrees C, and then to beta-Si3N4 structure when heated at temperatures higher than 1450 degrees C. Via spark plasma sintering (SPS) dense bulks with 97.9% relative density of theoretic value and the grain size of 100-300 nm was successfully fabricated at 1500 degrees C without any sintering additives.
